Which of the following is essential while riding to maintain visibility?

Using reflective clothing is essential for maintaining visibility while riding a motorcycle because it enhances the rider’s visibility to other road users, especially in low-light conditions or during poor weather. Reflective materials catch and reflect headlights from vehicles, making it easier for drivers to see motorcyclists from a distance. This increases safety by reducing the likelihood of collisions, as being visible can alert other drivers to the presence of a motorcycle.

On the other hand, adjusting your seat height primarily affects rider comfort and control but does not directly contribute to visibility. Maintaining a straight trajectory is more related to safe riding techniques and stability rather than visibility. Lastly, while using your horn can be useful to alert others of your presence, it does not help with making yourself visible to others in the same way that reflective clothing does.
